I trying to do stress testing using FOP. I right now using it as stand
alone Java application. When there are many FOP threads running at the
same time (>30), the JVM (java version "1.3.0_04") crashes with core
dump in Solaris m/c. It has greater impact when fop is used in an
application server, the application server will go down with FOP ! .

JVMs are not supposed to crash. FOP uses a lot of memory but you should always get a clean exception and a thread death whil the other threads run unaffected. It may have something to do with your JVM version, 1.3.0 isn't the latest release. Try upgrading to a more recent release first. On some (somewhat old) Solaris releases, a variety of applications which may include JVMs have been reported to have problems with many threads, they are ultimately killed by the kernel. Check the list of available patches for your Solaris release whether this is releated to your problem.
